Win Usa 5.56 55gr Fmj 20/1000 - WNQ3131KY

Winchester USA 5.56 NATO 55-grain Full Metal Jacket (FMJ) ammunition delivers consistent, reliable performance for military-pattern rifle training, qualification, and duty use. This M193-spec load represents the standard against which 5.56 NATO duty ammunition is measured—a proven cartridge engineered for velocity stability and reliable chamber feeding across platforms from service rifles to patrol carbines.

The 55-grain projectile paired with FMJ construction delivers the ballistic profile operators depend on for precision work at intermediate distances. This weight-velocity combination produces a flat trajectory suitable for zero distances common in law enforcement and military training protocols. Full Metal Jacket construction ensures reliable feeding through semi-automatic platforms and predictable penetration characteristics through intermediate barriers. Each 20-round box is dimensionally consistent, meeting NATO specifications for chamber pressure and velocity variance—critical factors for shooters who demand ammunition that groups cleanly and functions without malfunction across different weapon systems.

Winchester USA 5.56 NATO serves tactical training facilities, law enforcement qualifications, and military-pattern rifle enthusiasts who prioritize ammunition that performs as specified. Shooters conducting carbine courses, zero confirmation, and function-check drills benefit from the round-count efficiency of 20-round boxes—convenient for staged loading and range management. The M193 specification ensures interchangeability across standard 5.56 NATO-chambered rifles, making this load a logical choice for mixed platforms or departmental arsenals where ammunition commonality reduces logistics complexity.
